Preface 

In  accordance  with  the  expressed  wish  of  the  late  Doctor 
Ever'hart,  as  a  supplement  to  the  collection  of  woods  and  seeds  of 
Lackawanna  County,  which  he  was  making  at  the  time  he  was 
stricken  with  his  last  illness,  labeled  and  now  on  exhibition  in  the 
Museum,  I  presented  my  Herbarium  of  over  2,000  specimens  to 
the  institution  which  bears  its  founder's  name.  Incorporated  in 
the  Herbarium  is  a  practically  complete  collection  of  the  Flora 
of  this  part  of  the  state,  particularly  of  Lackawanna  and  Luzerne 
Counties. 

In  further  carrying  out  the  wishes  of  Doctor  Everhart  I 
have  prepared  this  check  list  of  the  Flora  of  the  above  region 
for  publication. 

A  preliminary  list  of  the  plants  in  the  Lackawanna  and 
Wyoming  Valleys,  of  which  Prof.  W.  R.  Dudley,  then  of  Cornell 
University,  was  the  author,  was  published  under  the  auspices  of 
the  Lackawanna  Institute  of  History  and  Science,  in  1887.  This 
volume  named  769  species  as  reported  and  classified.  In  1892, 
Professor  Dudley,  then  connected  with  the  Leland  Stanford  Uni- 
versity of  California,  and  Prof.  Charles  O.  Thurston  of  the 
Wyoming  Seminary  Scientific  Department  combined  their  per- 
sonal notes,  observations  and  collections  with  those  of  other 
students  of  local  botanical  research  and  issued  a  very  complete 
catalog  of  "The  Flowering  Plants  and  vascular  Cryptogams  found 
in  and  near  the  Lackawanna  and  Wyoming  Valleys."  This 
volume  contained  the  names  of  107  orders  and  974  species,  to 
which  there  were  later  addenda  of  88  species, — a  total  of  1,062. 
Of  this  number  several  have  since  been  considered  doubtful, 
while  others  have  become  exterminated  through  forest  fires  or 
advance  of  cultivated  areas  and  are  not  represented  in  this  check 
list. 

The  check  list  herewith  presented  contains  the  names  of 
115  orders  and  1,534  species.     The  specimens  have  very  largely 


been  collected  by  myself,  mounted  and  preserved  in  the  "Alfred 
Twining  Herbarium"  in  the  Everhart  Museum.  With  few 
exceptions  every  plant  named  in  this  Flora  is  represented 
in  the  above  Herbarium.  There  is  also  in  this  Herbarium  a  col- 
lection of  Filices  and  fern  allies, — an  almost  complete  representa- 
tion of  the  ferns  of  the  United  States,  and  many  foreign  ferns 
with  rare  and  odd  varieties  and  forms.  The  Orchidaceae, 
Liliaceae  and  Violaceae  of  the  eastern  half  of  the  United  States 
are  largely  represented  as  well  as  the  Cyperaceae  and  Gramineae. 
The  classifications  of  the  more  important  genera  have  been  veri- 
fied by  such  expert  authority  as  Prof.  Charles  S.  Sargent,  the 
late  Dr.  Thomas  C.  Porter,  the  late  Dr.  Thomas  Morong,  the 
late  Prof.  James  A.  Graves,  and  Prof.  E.  Brainerd. 

Outdoor  recreation  being  a  necessity,  as  well  as  a  great 
pleasure,  I  began  late  in  1900  the  collection  of  the  flora  over 
practically  the  same  range  of  territory  covered  by  Professors 
Dudley  and  Thurston,  as  well  as  amateur  collectors  reported  in 
the  1892  Flora.  In  preparing  the  appended  list  of  plants  I  have 
followed  the  classification  and  nomenclature  of  the  seventh 
edition  of  Gray's  Manual.  The  plants  recorded  in  this  Flora 
which  are  not  represented  in  Gray's  Manual  are  marked  with  a 
star  and  the  proper  authority  is  indicated. 

In  the  revision,  preparation  for  publication,  proof-reading 
and  effort  to  have  the  check  list  as  nearly  correct  and  authoritative 
as  possible,  I  have  had  the  kindly  and  generous  assistance  of 
Prof.  R.  N.  Davis,  Curator  of  the  Everhart  Museum,  whose 
love  of  the  woods  and  plant  life  first  led  me  to  the  study  and 
collection  of  our  local  flora.

INTRODUCTION 

A   flora   of    1,200  species   in   a   limited   area   is   considered 
rich;    when    334    species    are   added    to    this    number    there    is 
cause  for  wonder  to  botanists  not  familiar  with  the  topography 
of   the   country   from  which   the   local   flora   has   been   collected 
and  preserved  in  the  Herbarium  in  the  Everhart  Museum      The 
heart  of  the  Northern  Alleghenies,  where  the  tributaries  of  the 
Susquehanna,  Lehigh  and  Delaware  Rivers  have  their  rise    is  a 
beautiful  country  with  a  variety  of  soil  and  varying  altitudes 
We   have   many   lakes,   creeks,   tangled   swamps   and   bogs,   dry 
barrens,   rocks,   valleys,   plains   and  mountain   peaks,   with   drift 
heaps  of  the  glacial  age.     This  varied  topography  affords  local 
characteristic  types  as  well  as  the  plants  common  throughout  the 
Appalachian    region.      On   Bald   Mount,    Elk   Hills,    Penobscot, 
Pocono  and  Tilbury  Knobs,  and  the  Pocono  Plateau  and  marshes 
we  have  rare  plants  of  the  glacial  age.     We  have  Atlantic  slope 
species  whose  western  limits  of  distribution  are  within  our  border 
as  well  as  Southern  and  Southwestern  species  which  extend  no 
farther   north    or   northeast.      Over   fifty-five   northern    species, 
mainly  heaths  and  sedges,  are  found  here  which  do  not  extend 
south  of  our  territory. 

Among  the  more  notable  species  included  in  our  flora,  and 
represented  in  the  "Alfred  Twining  Herbarium,"  are  the  Arce- 
uthobium  pusillum,  Potentilla  tridentata,  Linnaea  borealis,  Vac- 
cinium  canadense,  Opuntia  vulgaris,  Picea  mariana,  Menyanthes 
trifoliata,  Liatris  scariosa,  Ledum  latifolium,  Rhodora  canadense, 
Andromeda  polifolia,  Kalmia  glauca,  Rhododendron  viscosum 
Gaylussacia  frondosa,  Chiogenes  hispidula,  Orontium  aquaticum, 
Melanthium  latifolium,  Amianthium  muscaetoxicum,  Arenaria 
groenlandica,  Cunila  mariana,  Pinus  inops,  Sedum  roseum, 
Asplenium  montanum,  and  Lycopodium  selago. 

While  the  leguminous  species  are  rare  on  the  Pocono  they 
are  abundant  in  the  two  valleys.  Quite  a  number  of  plants  which 
predominate  in  the  country  immediately  outside  the  Lackawanna 


9 


Valley  are  quite  rare  or  entirely  lacking  in  the  valley.  Among 
these  are  teasel,  hepatica,  dicentra,  claytonia,  bloodroot,  barberry, 
walking  fern  and  some  of  the  violets.  A  number  of  Southern 
and  Western  species  have  of  late  years  been  introduced  in  this 
region  through  the  railroads.  Weeds  that  were  rare  in  Lacka- 
wanna County  are  now  becoming  pests. 

Prof.  C.  S.  Sargent,  Director  of  the  famous  Arnold 
Arboretum,  a  world  authority  on  trees  and  shrubs,  after  three 
botanical  visits  to  Scranton,  expressed  the  opinion  that  there 
are  at  least  forty  species  or  forms  of  the  Crataegus  (hawthorn) 
in  the  Lackawanna  Valley.  Professor  Sargent  has  classified 
twenty-seven  of  these,  giving  the  handsomest  of  our  local  species 
the  name  of  Crataegus  twiningi.  This  species,  an  Intricatae,  is 
described  at  length  in  the  proceedings  of  the  Academy  of  Natural 
Sciences  of  Philadelphia,  Vol.  LXII,  Part  I,  1910,  pages  230 
and  231.  Professor  Sargent  adds  to  the  description:  "This 
species  is  named  for  its  discoverer,  Mr.  Alfred  Twining  of  Scran- 
ton, who  first  called  attention  to  the  richness  of  Lackawanna 
County  in  forms  of  Crataegus." 

The  following  interesting  points  and  altitudes  from  which 
the  greater  part  of  the  Flora  in  this  check  list  was  gathered  are : 
The  beautiful  double  domes  of  the  Elk  Mountains  (south  dome 
2,575  feet,  north  dome  2,700  feet),  exceeded  only  a  few  feet 
by  the  Blue  Knob,  the  highest  mountain  in  the  State ;  Bald  Mount, 
2,385;  Clarks  Summit,  1,239;  Elmhurst,  1,397;  Moscow,  1,555; 
Gouldsboro,  1,890;  Tobyhanna,  1,929;  Ararat  Summit,  2,023; 
Uniondale,  1,693;  Carbondale,  1,079;  Archbald,  965;  Pittston, 
573;  Kingston,  550;  Crystal  Lake,  1,755;  Campbell's  Ledge  (Dial 
Rock),  1,302;  Penobscot  Knob,  2,220;  Pocono  Knob,  2,225; 
Ararat  Peak,  2,600;  Sugar  Loaf,  2,450;  Mount  Anonymous, 
1,596;  Scrub  Oak,  2,092;  Big  Shiney,  2,320;  Moosic  Mountain 
Range,  from  2,000  to  2,120.
